【摘要】 目的 对作为高效物流运作关键载体的集装单元器具进行碳足迹核算研究，以促进绿色物流发展，落实“双碳”目标。方法 以某租赁企业铝合金材质托盘单元箱产品为研究对象，基于生命周期评价方法进行产品碳足迹核算研究。结果 完成了托盘单元箱生命周期6个阶段碳足迹核算，结果发现，托盘单元箱使用阶段和原材料生产阶段的碳足迹占比很大，而回收阶段碳足迹为负值，揭示了具有广泛应用及流动性的物流单元集装器具的生命周期碳足迹特质；提出废弃托盘单元箱回收再生利用、轻量化设计和创新托盘应用模式等降碳减排方案，并从托盘单元箱生命周期碳足迹以及货物周转量碳足迹进行了有效性验证。结论 回收再生利用、轻量化设计以及引入动态循环使用模式是实现托盘单元箱降碳减排的有效手段，研究为集装单元器具适应循环经济下的绿色物流发展提供了理论基础。更多还原

【Abstract】 The work aims to conduct carbon footprint accounting research on palletized unit implements, which are the key logistics appliances to ensure efficient logistics operations, so as to promote the development of green logistics and achive the "dual carbon(carbon peaking and carbon neutrality)" goals. The research on carbon footprint accounting of the aluminum alloy pallet unit box of a pallet rental company was based on the Life Cycle Assessment(LCA) method.Carbon footprint accounting was carried out for the six stages of the pallet unit box’s life cycle. It was found that the carbon footprint values of the use stage and the raw material production stage accounted for a very large proportion, while the carbon footprint value of the recycling stage was negative. The results revealed the inherent properties of carbon footprint of palletized unit implements which was characterized by their wide application and extensive mobility. For the aim of carbon reduction and emission reduction, proposals such as recycling and reuse of the waste pallet unit boxes,lightweight design, and innovations on the usage mode of pallet unit boxes were put forward. The proposals were verified by the lifecycle carbon footprint of the pallet unit box itself and also on its carbon footprint of goods turnover. It is proved that recycling and reuse, lightweight design, and the introduction of usage mode of dynamic recycling are efficient measures to achieve carbon reduction and emission reduction in the life cycle of pallet unit boxes.The research provides a theoretical basis for palletized unit implements to adapt to the development of green logistics under the circular economy.更多还原
